Fortress vineyards

Fortress is uncomplicated and straightforward

Our winemaking is relatively uncomplicated and straightforward: Focus on the vineyard, use time-honored, minimalist winemaking techniques, and let the fruit shine through. Fortress is largely estate-grown from vineyards situated on the ridges above Alexander Valley and hillsides at the base of Mount St. Helena in Knights Valley. Our winegrowing is guided by responsible farming practices that enable vines to produce smaller, intense fruit clusters, resulting in a wine with structure, weight and texture.
